BRIDGE FOR STRINGED INSTRUMENTS.

SPECIFICATION forming part of Letters IPatent No. 566,835, datedSeptember 1, 1896.

Application filed November 8,1895. Serial No. 568,265. (No model.)

To all whom it may concern:

Be it known that I, Huco AHLSTRAND, a citizen of the United States, anda resident of Everett, in the county of Middlesex and State ofMassachusetts, have invented new and useful Improvements in Bridges forString Instruments, of which the following, taken in connection with theaccompanying drawings, is a specification.

This invention relates to improvements in bridges for stringinstruments, particularly well adapted for guitars and mandolins, and itis carried out as follows, reference being had to the accompanyingdrawings, Wherein Figure 1 represents a top plan view of the invention.Fig. 2 represents a cross-section on the line 2 2, shown in Fig. 1. Fig.3 represents a cross-section on the line 3 3, also shown in Fig. 1. Fig.4 represents an end view seen from X in Fig. 1. Fig. 5 represents an endView seen from Y in Fig. 1, and Fig. 6 represents a sheet-metal blankfrom which the improved bridge is made.

Similar letters refer to similar parts wherever they occur on thedifferent parts of the drawings.

In the drawings, Figs. 1, 2, and 3, A represents the top sounding-boardof a guitar, mandolin, or similar string instrument for which myimproved bridge is used.

The bridge consists of a sheet-metal baseplate B, adapted to be secured,preferably by means of screws, to the top board A, as shown in thedrawings.

Integral with the plate B is made a curved longitudinal string-holder 0,having a series of circular perforations D, each about large enough toreceive one of the strings E, which is held in place by making a knot ethereon, as shown in Fig. 2.

Below each perforation D is made a somewhat larger perforation F, at theupper end of which is a rearwardly-projecting lip f, which latter servesas a smooth support for the string, which is passed through saidperforation F after going over and back of the string-holder O, as shownin Fig. 2.

G is the vertically-adjustable bridge-bar, which is guided betweenprojections H H, formed integral with the plate B, as shown.

I I are adjustingscrews screwed through the bar G and having their lowerends resting on the plate B, as shown in Fig. 8.

By adjusting the position of the screws I I the bar G may be raised orlowered, as may be desired, for the purpose of regulating the distanceof the strings from the finger or top board.

What I wish to secure by Letters Patent and claim is Theherein-described improved bridge for string instruments consisting of asheet-metal base-plate B having at its lower portion a curvedstring-holder 0 provided with perforations D, F and supporting-lips fand an adjustable bridge G guided on the base-plate and having adjListing-screws I for regulating the position of the strings relative tothe sounding-board substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 30th day of October, A.D. 1895.

HUGO AHLSTBAND.
